Question

At a hospital, 56 percent of the babies born are not girls. Of the baby girls born, 12 percent are premature. What is the probability of a premature baby girl being born at this hospital

Answers

  1. The probability of a premature baby girl being born at this hospital is 5%.
    The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event.
    If the likelihood of boys being born is 56%, then the complement of that is the likelihood of girls being born which is 100% – 56% = 44%.
    Since we are given that of the baby girls born, 12% are premature, the probability of a premature baby girl  being born is:
    (0.44)(0.12) = 0.0528 or 5.28%
    The closest answer is the 5%.
    The probability of a premature baby girl being born at this hospital is 5%.
